Description
Technical field
This utility model relates to a kind of ultrasonic osteotome bit for implantation of tooth.
Background technology
In the selection of anodontia repair mode, the repair mode of tooth plantation is more and more welcome.Compare with traditional repair mode, the repair mode of tooth plantation has maintenance good, and the more traditional artificial tooth of masticatory efficiency is improved largely, and is beautiful and comfortable, and the foreign sense does not damage the advantages such as tooth of closing on.
Traditional tooth plantation repair mode comprises following period: at first need treatment in 3 to 12 months after the exodontia, wait for knitting.Then, get out a hole with drill bit at original exodontia nest place, a traditional screw-like or cylindric implantation body are implanted in the hole that gets out in advance.At last, implantation body forms synosteosis after implanting some months, opens gingiva artificial artificial tooth is fixed in the implantation body.This type of implantation body's major part is titanium alloy, is processed into screw-like or cylindric, obtains through surface treatment again.This implantation body is batch production, and shape is single, and has very big-difference with the shape of natural root of the tooth, well the characteristic of the interlock of simulating nature tooth and conductance.
Carry out the tooth plantation and repair, just need to get in advance the hole ready at the alveolar bone place, existing standby hole mode all adopts machine bit directly to hole at alveolar bone agomphosis place.This standby hole mode can't prepare profiled holes, also may soft tissue injury, and the large photograph of heat production becomes excess Temperature.
Announced a kind of supersonic skeleton cutting instrument Chinese patent ZL98206710.0 number, comprised main frame and handle amount part, main frame comprises signal generator and power amplifier.Handle is comprised of the transducer that is in turn connected to form one, horn and cutter, and transducer is comprised of one group of longitudinal polarization piezoelectric patches, and cutter end cutter tooth adopts vertical sword formula structure.Power supply links to each other with transducer, makes transducer produce the vibration of single longitudinal ultrasonic and passes to cutter end cutter tooth by horn, implements the skeleton cutting operation.This ultrasonic bone cutting device has higher safety and accuracy, and is ultrasonic deep, and cutter shakes without the side without high speed rotating, effectively neuroprotective and blood vessel, thereby be widely used in spinal surgery, neurosurgery, department of otorhinolaryngology and plastic surgery.But, also this ultrasonic cutter is not applied in the implantation of tooth for the preparation of the profiled holes similar to natural tooth root at present.
The utility model content
For directly large in the osseous tissue wound that alveolar bone boring causes with drill bit in the implantation of tooth that overcomes, heat production causes greatly excess Temperature and can't prepare the shortcoming of profiled holes, and this utility model excess Temperature can not occur when a kind of, boring little to the osseous tissue damage is provided and can prepare the ultrasonic osteotome bit that is used for implantation of tooth of profiled holes.
The ultrasonic osteotome bit that is used for implantation of tooth, comprise union joint, the knife bar that is connected with handle and the cutter hub that is positioned at the knife bar front end, cutter hub comprises cervical region and daughter root, and daughter root is from cervical region to tip of a root convergent, the contour line of each daughter root is level and smooth curve, and the daughter root bending is nature root of the tooth shape; Cervical region covers daughter root fully overlooking on the direction, the outer surface of each daughter root section is coated with the Buddha's warrior attendant layer of sand for the cutting alveolar bone.
Further, the quantity of daughter root is 2-3, and side by side, cervical region covers all daughter root fully overlooking on the direction between the daughter root.
Further, the cutter hub cervical region is cylinder or Elliptic Cylinder; The cutter hub cervical region has the guiding fin that parallels to the axis, and the gathering sill of guiding die plate is adaptive when guiding fin and plantation.
Further, the cutter hub top is provided with outward extending flange, and the shoulder height of the plantation guide plate that adopts in the implantation of tooth determines the planting depth of implantation body, and the flange contact contacts the degree of depth that then expression reaches implantation body with step surface.
Further, the cervical region of cutter hub is provided with the graduation mark of the standby hole depth of sign.
Further, knife bar and handle are threaded connection.Handle is provided with external screw thread, and knife bar is provided with the female thread with the engagement of handle external screw thread.Knife bar is with after handle is connected, and dither is passed to knife bar and cutter hub from handle.
Further, union joint and knife bar connecting portion are by round-corner transition, and the diameter of knife bar is less than the diameter of union joint.
Further, knife bar is bent rod, and sweep is convenient to carry out standby hole operation in the oral cavity.
Further, there is psychrophore cutter head inside, can play the effect of logical cooling water.
Technical conceive of the present utility model is: the cross section of cutter hub cervical region is maximum, and the cutter hub root is from cervical region to the daughter root convergent, to guarantee the feasibility in the standby hole of alveolar bone.Cutter hub is made nature root of the tooth shape, and the Buddha's warrior attendant layer of sand by the cutter hub outer surface cuts alveolar bone, the plan nature tooth implant of the corresponding a kind of model of each osteotome.This utility model can be prepared the plantation nest adaptive with natural root of the tooth at alveolar bone, thereby so that like manufacturing and use and the natural thread form implantation body become possibility.
The piezosurgery osteotomy similar to implantation body implant part shape that provides with this utility model carries out standby hole.Ultrasound wave is after transmitting, and cutter hub produces the high-frequency microwave vibration, continues bump osseous tissue intermittently, thereby crashes and remove osseous tissue.Utilize piezosurgery osteotomy to perform the operation and more be conducive to process of bone healing, safer accurate, better control cellular inflammation, promote osteogenesis and reconstruction.
This piezosurgery osteotomy adopts cold cut to cut pattern, and the cooling water ejection is arranged in the endoporus of cutter head in cutting process, and a large amount of water smoke cooling of cavitation effect generation occurs by the vibration of cutter head, and heat production is few, cutting zone form rule, and cut-boundary is accurate.Utilize piezosurgery osteotomy to perform the operation and more be conducive to process of bone healing, safer accurate, better control cellular inflammation, promote osteogenesis and reconstruction.
This utility model can prepare the profiled holes similar to natural root of the tooth in order to implant the artificial growth body similar to natural root of the tooth, and can avoid nerve injury, can not occur the bone advantage such as burn during for the hole.
